Safety instructions
Wear safety goggles during drilling the guiding hole and during punching.
Keep hands out of the punching area during the punching process to avoid serious injuries.
Make sure
that
no other persons stay in front or close to the hydraulic punch
during the
punching process to avoid serious injuries caused by splinters at material failure or incorrect
use of hydraulic punch.
Before changing the punching inserts it’s absolutely necessary to remove the battery from the
device to avoid unintended use.
While operating it can come to sparking which could set fire on flammable or explosive
materials.
At intensive operating the hydraulic punch can be damaged because of overheating.
The hydraulic punch must not be operated in damp locations.
The punching process can be interrupted at any time by releasing the operating switch. Then
the hydraulic punch can be vented by pressing the vent lever.
Specified conditions of use
The Battery Packed Compact Hydraulic Punch is destined to punch metal sheets.

The optimal working temperature for the Battery Packed Compact Hydraulic Punch is between 15°and 25°C.
Description
The ALFRA Battery Packed Compact Hydraulic Punch is a hand operated device and is made up of the following
components:
1. Punching head head for the reception of the tension bolt including punch and die
2. Operating switch initiating of the punching procedure
3. Vent lever lever for vent of the punching head
4. Drive drive with operating switch
5. Battery rechargeable 18 V, 3,0 Ah NiMH battery
6. Punch Insert composed of punch and die to perforate the holes
7. Spacer sleeves 3 spacer sleeves in different strengths
Operating functions
The punching will be initiated through the activation of the operating switch. This switch must be pressed during the
whole punching process. After terminating of the punching process (if the punch has perforated completely)
unblock the switch. By pressing the vent lever once the piston moves backwards to its starting position.
If the hydraulic punch is strained to
the maximum pressure limit (due to improper tool
selection, incorrest spacers or false assembly) a higher pressure to the vent lever is
necessary.

Punching with round, square and oblong puncher
1. Pre-drilling with a twist drill or a multistep drill

2. Screw the hydraulic screw with the short thread side Ø 19,0 mm completely into the hydraulic cylinder.
3. Place the suitable spacer sleeves with the die on the hydraulic screw.
The application of a spacer sleeve is absolutely necessary.
4. Put the hydraulic screw through the pre drilled hole and screw in the round punch from the backside.

Pay attention on the right combination of punch and die. The diameter is stamped on
correspondingly.
Do not punch with incomplete screwed in punches. The whole thread turns of the punch have
to be screwed in on the hydraulic screw.
The punch should not hit the interior ground of the punch. This can cause damages to the tool
and on the hydraulic punching unit.
The punch must be screwed on, that a gentle contact with the sheet is given.

Operating time
The device is not suitable for permanent operation. After approx. 40 to 50 punching procedures a break should be
taken of approx. 10 to 20 minutes so the hydraulic punch cools down.
Technical data battery and battery charger

Battery and battery charger
The battery can be used both-sided for optimal counterweight to the punching tool.
No dissimilar batteries may be used in the charger.
The battery as well as the charger must be protected against humidity.
The charger is designed for a voltage of 230 Volt / 50 Hz.
Prod. No. 02071 Prod. No. 02072
New batteries must be fully charged before first use. For charging the battery put the plug of the charger into to the
power outlet and the battery into the charger. The charging time is approx. 45 minutes.
Do not work
with a feeble or partial discharged
b
attery, especially at application with large
diameter, square and oblong punches. The device could stop during the punching procedure
and it could come to damages.
Charge the battery, as soon as the speed of the hydraulic punching unit slows down.
The battery charge level can be read off an LED on the charging unit.
Green: battery is completely charged
Red: battery is empty and is charging
Blinking: battery is not completely inserted or battery is too hot. An acoustic signal sounds.
Do not charge a battery which is partial unloaded.
If you want to charge 2 batteries one after another, wait approx. 15 minutes before you load the
2
nd
battery.
